TR-CL180 Lens Controller - User Manual
Where:
d
= 0
to enable the keypad.
d
=1
to disable the keypad, but allow the unlock code
to be entered on the keypad
d
= 2
to disable the keypad and disallow the unlock
code to be entered on the keypad.
c
=
the unlock code, which must be a number from 0
to 255.
You can still access the TR-CL180’s settings using Ethernet
commands and through its web page. The settings of this command
are restored after a power cycle.
14.5 Analog mode commands
An analog input voltage from 0V to 10V can be used to set the focal power
of the lens connected to the TR-CL180. The translation from input voltage
to focal power can be linear or can be a non-linear profile. The non linearity
is set up by the number of steps in a translation table and the value
associated with each. The commands are described below:
Set analog mode
This command sets the output to analog mode so that the optical
power is set by an analog input voltage. The translation from input
voltage to focal power would normally be set before sending this
command.
RA1,0
Turn off analog translation
This command turns off the non-linear translation (enables linear
relationship), so that an input of 0V gives the minimum optical power
of the lens and 10V gives the maximum optical power of the lens.
RA1,1,0

This gives the following relationship:
Set analog translation
Non-linear translation can be used to convert the analog voltages
from a distance sensor to an optical power to focus at the given
distance.
This command turns on non-linear translation and sets the number
of steps in the non-linear translation.
RA1,1,n
Where:
n = the number of points in the profile (2 to 10)
This command sets a point within the non-linear translation:
RA1,d,f,a
Where:
d
the point to be set (0 to [number of points] - 1)
a
analog input voltage
f
equivalent focal power for the input voltage
The translation points are assumed to be valid.
Voltages below the first voltage are set to the focal power of the first
point. Voltages above the last voltage are set to the focal power of
the last point. Voltages between the points are interpolated
The points do not need to be in order. The controller will internally
sort them by analogue voltage.
